Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dialing system for telephones housed in exchanges. As one of the functions of increasingly diversified telephones, the telephone number of the telephone to which you make frequent calls can be registered in advance in correspondence with a dedicated call button for that telephone, and the registration can be completed by simply pressing the call button. A function that automatically sends a telephone number to an exchange and calls the telephone has been put into practice under the name of auto dial or one-touch dial.

0002

[Prior Art] In this kind of conventional dialing system, a telephone set is provided with a plurality of call buttons (hereinafter referred to as one-touch dial buttons) for calling the telephone of the party to whom calls are frequently made with a single operation. , when the phone user performs a predetermined registration operation,
The called person's telephone number is registered and placed in correspondence with each one-touch dial button, and the called person's name (name, company name, workplace name, etc.) is written on the label of the one-touch dial button.

[0003] When making a call to the called party from now on, by pressing the one-touch dial button on which the name of the called party is written, the telephone number registered in the telephone will be automatically sent, and the called party's telephone number will be automatically transmitted. You can call the called party and make a conversation without having to dial each one.

[0004] However, if the called telephone is busy, the connection is temporarily released and the call is made again. For telephones used within companies, etc., multiple telephones with different telephone numbers are installed in the same workplace (for example, in the same department), and if the called telephone is busy, The purpose of the call is often achieved by dialing back to another telephone.

[0005]Furthermore, telephones installed in the same workplace are often assigned telephone numbers that differ only in the last digit. In such a case, in consideration of the convenience of the caller to call back, if a call arrives at a telephone in a certain workplace and the call is busy, the caller will be able to call again without first releasing the busy call. In some cases, an exchange has a function to re-call another telephone by retransmitting only the lower digit of the other telephone's telephone number.

[0006] However, if a caller uses a one-touch dial button to call a telephone at a certain workplace and the called party is busy, the telephone number of another telephone at the same workplace may be different. Unless you have a one-touch dial button stored in your memory, your only option is to dial all digits or the last digit of the other phone's phone number to call again.

[0007]Furthermore, in many cases, the name of the called party is written on the one-touch dial button, but the telephone number is omitted, and it is difficult to find out the telephone numbers of other telephones in the same workplace without checking the telephone directory.

[0008] Even if the caller dials an adjacent telephone number while not knowing the telephone number of the other telephone, there is no guarantee that the desired office telephone will be called.

[0009]

[Problems to be Solved by the Invention] As is clear from the above explanation, in the conventional dialing system, as a result of automatically transmitting a registered telephone number with a single operation of a one-touch dialing button, the called party If the call is busy, in order to call back to another nearby phone, it is necessary to release the busy call, check the phone number of the other phone, and then call again. There were problems that impaired the convenience of the telephone.

SUMMARY OF THE INVENTION An object of the present invention is to simplify as much as possible the operation when making a call again when the called telephone is busy by operating a one-touch dial button.

[0011]

[Means for Solving the Problem] FIG. 1 is a diagram showing the principle of the present invention, and FIG.
), and Figure (b) shows the principle of the present invention (claim 3).

In FIG. 1, reference numeral 20 indicates a telephone set, which is the object of the present invention, and 30 indicates a telephone line for accommodating the telephone set 20 in an exchange (not shown). Reference numeral 100 denotes a number registration means provided in the telephone 20 according to the present invention (claims 1 and 2).

[0013] 200 is the present invention (Claim 1, Claim 2)
This is a busy detection means provided in the telephone 20. 3
00 is the telephone 2 according to the present invention (claim 1, claim 2)
This is a display means provided at 0.

Reference numeral 400 denotes a number registration means provided in the telephone 20 according to the present invention (claim 3). Reference numeral 500 denotes a dialing number incrementing means provided in the telephone 20 according to the present invention (claim 3).

[0015]

[Operation] The number registration means 100 groups a plurality of telephones that differ only in the lower digit of the telephone number, and registers the telephone number (DN) of one telephone in the group, and registers the telephone number (DN) of one telephone in the group, and registers the telephone number (DN) of one telephone in the group. The lower one digit (DX) of a telephone number is registered in advance, and when a call button corresponding to the group is operated once, the registered telephone number (DN) is automatically sent to the exchange.

Busy detection means 200 detects whether the called party is busy when a call is made from telephone 20. When the busy detection means 200 detects that the called party is busy, the display means 300 extracts the lower one digit DX registered in the number registration means 100 and displays it to the user. When an arbitrary number is selected from the displayed lower one digit DX, the selected lower one digit DX is sent to the exchange.

[0017] When the user selects an arbitrary number from the displayed lower one digit DX, the display means 300 displays the previously sent call after once releasing the call that occurred during the call. Consideration is given to changing the lower digit of the telephone number DN to the lower digit DX selected by the user and re-calling the exchange using the changed telephone number.

Therefore, according to the present invention (claims 1 and 2), when a telephone corresponding to a registered telephone number is busy, the last digit of the telephone number of another telephone in the same group is will be displayed, and by dialing the displayed lower digit or a new phone number with the lower digit changed from the last phone number sent, you can call the other phone even if you do not know the other phone number. It becomes possible to easily call back to the telephone, and the convenience of the telephone is greatly improved.

The number registration means 400 registers in advance the telephone number DN of a telephone set housed in the exchange, and automatically sends the telephone number DN to the exchange when a call button corresponding to the telephone is operated once.

[0020] When the sending number incrementing means 500 sends the registered telephone number DN to the number registration means 400, the user recognizes that the called party is busy, and instructs the user to input the predetermined telephone number DN. After detecting that the caller has performed an increase/decrease operation, and once releasing the call that occurred during a busy call, the previously sent telephone number DN is increased/decreased to the first destination in accordance with the increase/decrease operation, and then the number after the increase/decrease is Resend the telephone number DN to the exchange.

Therefore, according to the present invention (claim 3), when the telephone corresponding to a registered telephone number is busy, the operation of re-dialing to another telephone whose telephone number is most different is greatly simplified. This greatly improves the convenience of the telephone.
